Location-targeted online services

ABSTRACT

Described are various implementations of location-targeted online services. When a user accesses the Internet from a supported location, he&#39;ll be able to use premium or exclusive online services (premium content, member-only discounts etc.) for free and without going through an elaborate subscription process. The location owner may promote these services before the user enters the location. Example: in addition to mentioning “free Internet”, the hotel owner can attract new customers by mentioning “free Netflix movies” or “free access to premium content, from Zagat reviews to stock reports”. It allows the location owner to utilize a network (WIFI) service provider as a means of increasing its core business and not just as a source of incremental advertisement income.

CROSS-REFERENCE TO RELATED APPLICATION

This regular U.S. patent application is based on and claims the benefitof priority under 35 U.S.C. 119 from provisional U.S. patent applicationNo. 60/982,706, filed on Oct. 25, 2007, the entire disclosure of whichis incorporated by reference herein.

FIELD OF THE INVENTION

The present invention generally relates to internet technology and, morespecifically, to providing various services to customers over a computernetwork.

DESCRIPTION OF THE RELATED ART

Web sites and services requiring users to pay for the content severelylimit the user base. Sites utilizing free trials and limited-time offersstill attract fewer users than sites with completely free content.However, converting from a paid content model to a free content model isrisky since traffic may not grow fast enough to generate comparable adrevenue.

The same problem also applies to member-only discount clubs (cruisediscounts, etc.), which use exclusivity to justify their specialpricing; any access limitation drastically decreases the user base.

Thus, there is currently no existing conventional methodology whichallows premium web sites and services to expand their user base withoutcompletely switching to free content. Furthermore, there is currently noexisting technology which allows member-only sites and services toexpand their user base without completely dropping subscriptionrequirements.

SUMMARY OF THE INVENTION

The inventive methodology is directed to methods and systems thatsubstantially obviate one or more of the above and other problemsassociated with conventional techniques for providing services tocustomers over a computer network.

One aspect of the inventive concept is a system, method andcomputer-readable medium for providing location-targeted onlineservices.

Additional aspects of the inventive concept include a system foraccessing premium content, which includes a user computer initiating arequest for premium content, a proxy server operable to obtain anauthorization cookie, append the authorization cookie to the request forpremium content and forward the request for premium content, and acontent server receiving the forwarded request and returning premiumcontent upon detecting the appended authorization cookie.

Additional aspects of the inventive concept include a system foraccessing premium content, which includes a user computer initiating arequest for premium content, said request containing first cookie, saidcookie being different from the authorization cookie required toretrieve requested content, a proxy server operable to modify firstcookie to produce the authorization cookie, append the authorizationcookie to the request for premium content and forward the request forpremium content, and a content server receiving the forwarded requestand returning premium content upon detecting the appended authorizationcookie.

Additional aspects of the inventive concept include a system foraccessing premium content, which includes a user computer initiating arequest for premium content which is redirected to a partner webservice, wherein the partner web service modifies request for premiumcontent by using a modified URL link, a content server comprisingpremium content, and a proxy server which operates to process themodified URL link into a URL link associated with the content server,redirect the user computer to the content server and retrieve premiumcontent.

Additional aspects of the inventive concept include a system foraccessing premium content, which includes a user computer initiating arequest for premium content, said request containing first universalresource locator (URL) comprising host portion and a query portion, thehost portion being the same as the host portion of URL of the contentserver, and a proxy server which operates to modify the query portion ofthe first URL, append modified query portion to the host portion of thefirst URL to produce second URL addressing the requested premiumcontent, request the premium content referenced by the second URL andretrieve premium content.

Additional aspects related to the invention will be set forth in part inthe description which follows, and in part will be obvious from thedescription, or may be learned by practice of the invention. Aspects ofthe invention may be realized and attained by means of the elements andcombinations of various elements and aspects particularly pointed out inthe following detailed description and the appended claims.

It is to be understood that both the foregoing and the followingdescriptions are exemplary and explanatory only and are not intended tolimit the claimed invention or application thereof in any mannerwhatsoever.

DETAILED DESCRIPTION

In the following detailed description, reference will be made to theaccompanying drawing(s), in which identical functional elements aredesignated with like numerals. The aforementioned accompanying drawingsshow by way of illustration, and not by way of limitation, specificembodiments and implementations consistent with principles of thepresent invention. These implementations are described in sufficientdetail to enable those skilled in the art to practice the invention andit is to be understood that other implementations may be utilized andthat structural changes and/or substitutions of various elements may bemade without departing from the scope and spirit of present invention.The following detailed description is, therefore, not to be construed ina limited sense. Additionally, the various embodiments of the inventionas described may be implemented in the form of a software running on ageneral purpose computer, in the form of a specialized hardware, orcombination of software and hardware.

A location owner may not be interested in the relatively low incomegenerated from Internet advertising. For example, a coffee shop ownerwith ˜100 ad views/day may generate revenue of $7.5/month at $5 CPM, ata 50% revenue share. A hotel with ˜3000 ad views/day: may generaterevenue of $225.month at $5 CPM, at a 50% revenue share, which is lessthan the price of Internet access in a single room if the hotel charges$10/day.

Thus, it would be desirable to use a location-based service to attractnew customers to location's core business.

On the other hand, users feel that paid Internet services should notcarry additional advertisements. Thus, if hotel charges each user$10/day for internet access, users may accept a small hotel toolbar onevery page, but not full-size ad banners. Thus, it would be desirable tojustify the display of additional 3rd-party offers on locations withpaid Internet access.

Moreover, multiple WiFi networks may cover the same location. Forexample, Union Square in San Francisco is already covered by multipleWiFi networks; some of them displaying content without additional ads.If a flat-rate paid nation-wide 3G or WiMax becomes ubiquitous (forinstance, users drop land-based access and keep only WiMax), the userwould not have an incentive to use local WiFi networks withadvertisements. Thus, it would be desirable to provide an incentive touse a WIFI service, even if other means of Internet access are availableat the same location.

The future WiMax network blurs location targeting. WiMax covers up to 20miles, which makes it difficult to target separate businesses, even iffree WiMax uses an ad insertion mechanism. If free WiMax is available inthe area, the user would not have an incentive to use local WiFinetworks with advertisements. Thus, it would be desirable to provideincentive to use small-range WiFi when free WiMax is available at thesame location.

Various Embodiments of Inventive Concept

One embodiment of the inventive methodology enables location-targetedonline services. When a user accesses the Internet from a supportedlocation, he'll be able to use premium or exclusive online services(premium content, member-only discounts etc.) for free without goingthrough elaborate subscription process.

The location owner may promote these services before the user enters thelocation. For example, in addition to mentioning “free Internet access”,the hotel owner can attract new customers by mentioning “free Netflixmovies” or “free access to premium content, from Zagat reviews to stockreports”. It allows the location owner to utilize a service provider(such as WIFI or other network service provider) as means of increasingits core business and not just as a source of incremental advertisementincome.

Offered services will also be promoted on the supported location asadvertisements appearing during web browsing on the entry page. Becausesuch promotions remind the user of pre-announced exclusive benefits, theuser may accept additional advertisements even while paying for Internetaccess.

If the same location is covered by multiple networks (hotel LAN, muniWiFi, Sprint WiMax etc.), the user will be reminded to choose anetwork-provider-supported network to enable the exclusivelocation-targeted services. For instance, the WiFi network may be named“BedBreakfastAndFreeMovies” or “OnlineTravelDiscounts”.

Even if free WiMax is available in the same area, the user will stillbenefit from using the location-targeted WiFi services (for instance,bookstore offering free online access to member-only reference materialsand e-books).

After the user starts accessing the premium content or the member-onlyservices, the service provider will show a reminder that this benefitwill end when user leaves the location. To keep the access, the userwill have to start paying for services, or formally enroll into thetrial period, or submit personal info to qualify for a freesubscription. In this way, the service provider will provide premiumcontent services with a way to recruit new users who are alreadyfamiliar with the product.

Free access to a location-targeted service will be automaticallydisabled after user leaves the service provider's network. The user willbe able to continue accessing the same service only if he starts payingor becomes a member. This automatic disconnection from the service isanother aspect of the inventive methodology.

Optionally, free access to the same premium service can be automaticallyre-enabled as soon as user enters the same or related location supportedby the service provider. The premium service will recognize repeatcustomers and preserve their preferences, but only while these customersare at supported locations.

In one example of a location-targeted service: customer at the hotelautomatically gets access to free movie streaming, as if he is alreadyenrolled into the trial period.

In another example of a location-targeted service: while staying in thehotel, the customer automatically gets access to premium online content,at least for publications that are already distributed for free in theprinted form (for instance Wall Street Journal is available in mosthotels for free, but online content is not). Other content providers maynot require a subscription fee, but still require the customers toregister. The service provider can provide automatic log on whilecustomer is on location.

In another example, the location-targeted service is asubscription-based restaurant review, such as Zagat, or a restaurantreservation service. In this and other examples of the location-targetedservice: customer in the hotel is automatically recognized as a memberwith access to member-only content.

In one other example, the location-targeted service provides premiuminvestment information provided by market research or brokerage firmsuch as ShortSqueeze, Forrester Research, Schwab, orSmartMoney—limited-distribution stock recommendations, premium stockanalysis, member-only real estate information etc. In yet anotherexample, the location-targeted services provides member-only discountclub (SmartCruises, etc.) without the need for user login to accessmember-only content.

To advertise the location-targeted service, large hotels may advertiseonline; motel chains may show posters on premises: instead of “FreeInternet”, it may say “Free Internet, free movies”.

In another example, location-targeted services provide free trialsubscription to audiobooks, or premium reference services, or onlinelibraries,

The location-targeted service may also be deployed in a shopping mall toprovide users with free and easy access to subscription-only onlineproduct reviews and ratings (Consumer Reports, CheckBook, Angie's Listetc.), allowing the customer to check product ratings while inside themall without going through subscription process.

Location-targeted services may also provide free subscription to a musicservice (Napster, Rhapsody, Virgin etc.) for users in a coffee shop, orfree trial subscriptions to online movies from Netflix or Blockbuster.

Support for location-targeted services should include most of followingfeatures:

-   -   easy activation of the targeted member-only service, preferably        without forcing the user to provide any information to become a        member (users outside the location will have to subscribe as        usual).    -   automatic recognition of the same user during multiple sessions        at the same location.    -   a reliable way to automatically disconnect access to the        member-only service outside the location, unless user        deliberately requests to continue the service.    -   automatic recognition of the same user upon re-entering the        location with targeted service.

To support these features without an intermediary such as a serviceprovider, requests from a location network must be authenticated by alocation-targeted service. This would require changes on both sides ofthe exchange, making location-targeted services impractical for bothlarge vendors with change-resistant infrastructure and for small vendorsthat don't use strong authentication.

The WIFI service provider, serving as the “man-in-the-middle” for anytransaction between the location and location-targeted service, willseamlessly modify traffic between both parties to provide all the listedfeatures without requiring any additional support.

As soon as customer leaves the service provider's network, thesereal-time modifications will disappear, automatically disabling targetedservices even if the user continues the same browsing session.

In this way, the service provider makes location-targeted servicestransparent for both location and online service, eliminating barriersto their deployment

Demonstration of the advantages of location-targeted service may comparethe experience with and without directing traffic through the serviceprovider's proxy server. The latter is equivalent to an experience onthe targeted location, where all traffic is redirected through either alocal or a remote service provider's proxy.

Alternatively, instead of changing proxy on the browser, the on-sitedemo may switch between 2 different networks: one that supportslocation-targeted service, another that does not.

Example of such a demonstration may include the following steps:

1. Default (proxy disabled):

-   -   user tries to access premium service (Netflix, ShortSqueeze        etc.): not recognized and thus must sign-in or enroll as new        user.

2. New location-targeted service technology (same browser session,enable proxy):

-   -   advertisement on a current site offers one-click access to the        service (“no sign-in needed while you are at this location”)    -   user clicks on the ad and gets full access to the service        without log-in    -   while service is used, advertisement offers to sign up to        continue after leaving the location

3. Default again (same browser session, disable proxy):

-   -   user tries to continue with the service, but is requested to log        in or sign in as a new user.

4. New location-targeted service technology again, (same browsersession, enable proxy):

-   -   on seeing the ad offering one-click access, user bookmarks the        link, in order to use the service after leaving the location

5. Default again (same browser session, disable proxy):

-   -   user selects the bookmark, but sees only the offer to sign in.

6. New location-targeted service technology again (same browser session,enable proxy):

-   -   user selects same bookmark and gets full access to the service        without the log in.

One embodiment of targeted services comprises a location-specificmembership: Different requirements to become a member, depending on thelocation where the online service is accessed, or depending on theaccess network.

In normal mode, the user must enter some information to enroll (selectuser name, select password, in some cases enter additional informationsuch as email address, age, gender, interests etc.).

FIGS. 1 a-1 f shows the prior art sign-in process, where first requestedcontent is supplied from the content server 102 only after user entersname and password; subsequent content during the same session isauthorized if the user computer 101 contains a cookie stored duringsign-in.

In the present invention, the barrier to enroll is lowered on thetargeted location or on the targeted WiFi network: a first-time user canaccess the service just by clicking on its link (bypassing enrollment orsign in), or the user name and password are already provided for easysign-in, or the user must enroll but isn't required to provide extensivepersonal information.

In this way, targeted service may incrementally extend its user base,without dropping membership or payment requirements for all users.

In one implementation, location-specific membership works only while theuser is at the targeted location. Upon leaving it, the user must performadditional steps (submit additional information, start paying etc.) tocontinue using the service.

Alternatively, a location-specific membership continues to work afterthe user leaves the location. The content provider may requireadditional steps (for instance, payment) after the trial period expires,but will not force the user to submit additional information just tocontinue trial period.

The same content provider may utilize different ways to extendlocation-specific memberships for different users leaving targetedlocation, and then select the method producing the best results.

In the described implementation, a location-specific membership dependson the availability of the proxy server for forwarding requests andresponses between the user's computer and content servers. Such a proxymay, for instance, reside on a wireless router at the targeted location,or on a remote server used to redirect HTTP traffic from the localnetwork at the hotel.

FIGS. 2 a-2 d show an implementation where the proxy server 206 obtainsan authorization cookie 202 from storage 203, and then appends it to theuser's request 204 to obtain first content without sign-in 205. If theuser computer 200 issues the next request 207 to the same content server201 after leaving the location, there is no proxy server to add theauthorization cookie, and the user request is redirected to theinvitation to sign in 208.

FIG. 3 shows another instance of the present invention by identifyingthe user by the originating IP address. In this case, the content server301 has to be supplied with list of IP addresses corresponding to targetlocations; this list must be regularly updated. In comparison withlocation-specific links supported by the proxy server, thisimplementation requires additional support from a location-specificservice.

In one other instance, the targeted location and the location-specificservice may utilize fully authenticated exchange mechanisms, forinstance by using Radius servers before the location-specific service isprovided. In comparison with location-specific links supported by proxyserver, this implementation requires additional support both fromtargeted location and from location-specific service

Another embodiment of targeted services comprises location-specificcookies:

First, user's computer sends a request to fetch content from a contentserver. As part of the response, the content server sends a cookie to bestored on user's computer. However, this cookie is replaced by anotherone that hides at least part of the data the content server wanted tostore on user's computer.

In one example, the content server sends a response to the proxy serverwhich performs a cookie replacement and then sends a response with areplaced cookie to the user's computer. While the user is at thetargeted location, this proxy server is responsible for forwarding alltraffic between the user's computer and the remote content servers.

For instance, the user's computer may be wirelessly connected to arouter that is running proxy software, or the user's computer may beconnected to a wired local network that redirects all traffic through aremote proxy server. In both examples, the cookie on the user's computeris replaced only if the user receives a response from a content serverwhile being connected through the proxy associated with the targetedlocation.

Cookie data can be hidden in 2 different ways:

-   -   data sent by the content server is encrypted and then stored on        the user's computer, or    -   data sent by the content server is stored outside of the user's        computer (for instance, in the indexed database table on a        remote server), while only a pointer to that data is stored on        the user's computer.

Then, after a modified cookie is stored on user's computer, the samecomputer issues another request to fetch content from the same contentserver, sending the stored cookie as part of the request.

If this request is forwarded through the proxy server associated withthe targeted location, the proxy server replaces the cookie with the onecontaining data originally sent by the content server. The contentserver receives data previously sent to the user's computer, recognizesthe user and serves the requested content. In this way, a user connectedthrough the proxy and associated with the targeted location continues tointeract with the content server as if content server cookies werestored without any modifications.

However, if the content server receives a content request accompanied bythe cookie as it was stored on user's computer, it will not be able tounderstand the modified cookie. If the content server doesn't recognizethe user, it may decline to provide the requested content until the userconfirms his identity, or will fail to provide the personalized content.In this way, a user leaving the location associated with the proxyserver that performed cookie modifications is prevented from receivingthe same content, at least until performing the additional stepsrequired to get accepted by the content server.

Cookie data can be restored in 2 different ways:

-   -   encrypted data is decrypted before sending a request to the        content server, or    -   a pointer, such as a index stored on user computer, is used to        retrieve data stored outside of the user's computer (for        instance, on a remote server), and then pass the data to the        content server.

FIGS. 4 a-4 f show one embodiment, where the user logs in 402, causingthe server 401 to set an authorization cookie 403, encrypted by a proxyserver 406 and stored on the user's computer 400. While the usercontinues to send requests through the proxy server, the cookie suppliedwith the next request is decrypted 404 before being sent to the contentserver 401. The content server responds with the requested content 405and updates the cookie to reflect the user's browsing history 407. Ifthe user issues another content request without assistance from theproxy server as shown in 408 (for instance, after leaving the targetedlocation), the cookie isn't decrypted, causing the encrypted cookie tobe sent 409. The content server won't recognize the user and will eitherrespond with a sign-in request or just re-starts collecting browsinghistory if the latest content request didn't require authorization 410.

FIGS. 5 a-5 f show another embodiment, where the cookie supplied by thecontent server is stored separately (for instance, on the remote server502), while only the index referencing that storage 503 is sent to theuser's computer 500. While the user continues to send requests throughthe proxy server 506, the cookie supplied with the next request isde-referenced from storage 504 before being sent to the content server;the content server 501 then responds with requested content, updatingthe cookie to reflect the user's browsing history 505. If the userissues another content request without assistance from the proxy serveras shown in 507 (for instance, after leaving the targeted location), thecookie isn't de-referenced 508, the content server doesn't recognize theuser and either responds with a sign-in request, or just re-startscollecting browsing history if latest content request didn't requireauthorization 509.

Examples of using location-specific cookies:

A. Location-specific service as described above: user continues to getrecognized as a member while on targeted location, but this recognitionends as soon as user leaves the network associated with the proxy thatmodified the cookie.

When the user re-enters the same or a different location (for instance,another hotel in the same group) that knows how to restore data from themodified cookie, the user will get recognized again and can thereforecontinue to use the targeted service.

B. Location-specific user identity. Multiple sites and advertisingnetworks try to track user's behavior through search requests, interestto specific products etc. While useful to for providing personalizationand relevant advertisements, such tracking over the long period of timecan violate user's privacy.

Location-specific cookies enable creating separate identities fortargeted locations.

B1. In one implementation, a modification of the cookie sent by thecontent server includes changing both its name and its value. In thesame implementation, the proxy server blocks every cookie that was notmodified from reaching the content server.

While the user is at the targeted location, the content server doesn'thave access to the old cookie and thus treats the user as a differentidentity. After the user leaves the targeted location, the contentserver starts receiving an old cookie, together with the one modified bythe proxy server. While ignoring the modified cookie, the server nowrecognizes the user's identity from the old cookie and remembers actionsperformed before the user was at the targeted location.

When user enters a targeted location again, the process repeats itself:now the content server reads only modified cookies, reflecting only theuser history at the targeted location. In this way, the userautomatically switches identities while entering and leaving thetargeted location. For instance, the user's browsing history while inthe supported bookstore or hotel will not be correlated with thebrowsing history when the same notebook computer is connected toInternet at work.

B2. In another implementation, modification of the cookie sent by thecontent server includes changing only the cookie value; the cookie nameremains the same.

In this case, the content server stops recognizing cookie value andforgets user history after the user leaves targeted location,effectively erasing the old user identity. If proxy server also blocksany unmodified cookies from reaching content server, previous identityis erased first on entering and then on leaving targeted location.

One other embodiment of targeted services comprises location-specificlinks.

In U.S. patent application Ser. No. 11/292,187, incorporated byreference, the user requests are re-directed to a partner web service.If the service provider's service isn't present, a click on the sameleads directly to the target content server.

In contrast, a location-specific link leads to the intended contentserver only if a service provider's service is present; in absence of aservice provider's service, a click on the same link doesn't reach itsintended target.

To accomplish that, the URL associated with the link and referencing thenetwork address of the specific content server is modified, so thatadditional assistance is required to uncover the hidden address of thatserver before content request can be sent to its intended destination.

In one implementation, this assistance is provided by a proxy serverthat forwards user requests to all content servers. For instance, theuser's computer may be wirelessly connected to a router having runningproxy software, or the user's computer may be connected to the wiredlocal network that redirects all traffic through a remote proxy server.

If URL modification includes encrypting the address of the targetcontent server, the proxy server decrypts this address for every requestwith encrypted URL and redirects it to the correct location.

Alternatively, correct addresses of the target server can be stored in aseparate database, with the URL of the location-specific link containingan index referencing such database. In this instance, the proxy serveruses this index to obtain correct address of the target content serverand re-direct the user request to a correct destination.

In this way, a click on a location-specific link works as expected(fetches content from the target content server) only while the userrequests are sent through the proxy server. If this proxy server isassociated with a specific location (resides on a wireless router, orprocesses traffic re-directed from the local network), thelocation-specific links works only while user is at supported location.

In one implementation, the location-specific link stops working afterthe user leaves supported location, or switches to the network wheretraffic isn't forwarded through the decoding proxy. For instance, suchan encoded link may point to an encrypted server name that doesn'tcorrespond to any real network address.

FIGS. 6 a-6 c depict such an implementation, where a link on the user'scomputer 600 references a URL with an encrypted combination of the hostname and a content path 602. After the user clicks on that link torequest the content, the proxy server 606 decrypts both host name andpath, resolves the decrypted host name (abc.com) to an IP address withhelp from the DNS server 603, adds the decrypted path (content.html) andsends a fully formed request to the content server 604, causing it toreturn the requested content 605.

If a user performs the same click outside of the location supported bythe proxy server as shown in FIG. 6 c, the encrypted URL is sent to theDNS server 607 which returns a “Server not found” error 608 and the linkis disabled.

In another implementation, a click on a location-specific link performedoutside of the supported location does send a request to the intendedcontent server, but specifies a default or sign-up page (encodedlocation of the intended content is stored in the query, ignored by thecontent server). As a result, the user outside of a supported locationmay see, for instance, a sign-up page inviting to subscribe to theservice, instead of requested content.

FIGS. 7 a-7 d depict an embodiment where the link stored on user'scomputer contains the correct content path, with only the query portionof the URL being hidden (references remote storage). This depiction, aswell as the other figures except for FIGS. 6 a-6 c, omits theinteraction with DNS servers in order to simplify the description. Theproxy server 706 retrieves the correct query 702 from the storage 703and sends a complete request 704 to the content server 701. The contentserver then returns content personalized for the user as identified bythe query 705.

If the user performs the same click outside of the location supported bythe proxy server as shown in FIG. 7 c, a URL with a hidden query 707 issent to the content server, which subsequently can't recognize the user(FIG. 7 d) and thus returns generic (non-premium) content or aninvitation to log in 708.

In an alternative implementation, the link is left unmodified, but theproxy server adds a cookie to the request with known URL in order toreceive specific content. For instance, many sites perform an automaticlogin for recognized users: if an appropriate cookie is received, theuser clicking on the same link is accepted as a member; if not, the useris presented with a login page. With an agreement from thelocation-specific service, the proxy server may pre-store anauthorization cookie that belongs to a different user and supply it witha requested URL for that service.

Examples of using location-specific links:

A. Login-free access to a member-only service.

In one implementation, the user name and password are included into theURL: any person accessing that URL would be able to bypass the loginprocess. However, the URL stored on user's computer is encrypted; it isconverted to a form recognized by the content server by a remote proxy,outside of user's control.

For instance, an advertisement offers a no-login trial period while theuser is at a targeted location. The user may click on the advertisementto bypass the login. However, if the user tries to bookmark the URL anduse it outside that location, the same link will not work.

In another implementation, an encoded URL points to the page with thedesired content (for instance, advertised movie), which can normally bereached only after logging in. A user clicking on the link causes theproxy server to decode the URL and to add a previously acquired cookieconfirming that the user has a right to access desired content.

Such a cookie may be pre-stored on the remote server, for instance, byre-using a cookie first generated for another user.

B. Location-targeted product discount

In one implementation, the coupon code is included into the URL, whichis stored in an encrypted form on the user's computer; access to thatURL will automatically discount the price for the referenced product.

For instance, an advertisement offers to purchase an online product at adiscount price, but only while the user is at specified location. If theuser tries to bookmark the URL and use it outside that location, thesame link will not work.

Yet one other embodiment of targeted services compriseslocation-targeted online services

The main sequence of steps for location-targeted services is:

-   -   while the user is outside of the targeted location, advertise        the user's benefits if the online service or product is consumed        from the targeted location. To differentiate from offers on the        local sites (for instance, the login page of the hotel), the        same service or product should be also available outside of        targeted location, but on less favorable conditions.    -   after the user enters the targeted location, provide the user        with access to the advertised benefit.    -   after the user leaves the targeted location, disable access to        the advertised benefit, or ask the user to perform additional        actions (sign in, etc.) to maintain the access.

FIGS. 8 a, 8 b, 9 a and 9 b depict one embodiment of this sequence.

While outside of the targeted location (FIG. 8 a), the user opens thebrowser window 810 and searches for the nearest book store (input field820, search query 840). The resulting search results contain a list ofdescriptions of nearest book stores with at least some descriptionsbeing provided by the stores themselves to entice users to visittargeted locations. For instance, XYZ Books (search result 2) advertisesavailability of the free Internet access. However, ABC Books 830promises not only free Internet access, but also ability to freelybrowse premium or restricted content (online books) during the visit tothe store.

The user then visits the store that provides the best incentive, andopens the browser window while using the local Internet connection (FIG.8 b) and downloads the main content 870 together with the link thatenables the user to access the promised premium content. In the depictedembodiment, such a link is presented as part of the advertisement 850,which can be either embedded into the main content 870 or added to it bythe proxy server. Such a proxy server can be, for instance, installed ona wireless router serving the current location.

Alternatively, such a link can be integrated with the main document, forinstance as being a part of the bookstore's web site.

The user can observe the URL referenced by the link in the status bar880, but this URL will work only while the user is at the specifiedlocation.

If the user positions the cursor 860 over the link associated withlocation-targeted service and then performs a click, the requestedcontent is presented immediately (FIG. 9 a), without any additionalsteps. While the user is on location, he can continue to browse offeredcontent 901.

If user attempts to access the same service after leaving the location(FIG. 9 b), he is presented with a request to become a member 902, whichrequires the user to provide additional information that can be used formarketing purposes, or pay for subscription.

The depicted embodiment combines the location-specific membership(different requirements to become a member depending on location), thelocation-specific cookie (user can continue browsing while on location,but not after leaving the location) and the location-specific links(even if user bookmarks the link, it will not work outside thelocation).

However, the location-targeted online services do not depend on any ofthese features.

In an alternative embodiment that doesn't rely on location-specificcookies or links, the location-targeted service this sequence creates isa customized web site and provides it to the location owner for storageon the local network. For example, the online retailer may create acustom page with selected products at discount prices, to be stored onthe local server at the targeted location. The users will see that pageonly while on the targeted location, but will still be able to purchasethe same products, albeit without a discount, from the main site of thesame retailer.

The main differentiator of the location-targeted service from theadvertisement selectively shown at specific location is the fact thatthe user benefit (one-click membership, exclusive product discounts,etc.) is advertised before the user enters the location, so that user isgiven an additional incentive to visit the location.

In another implementation, access to premium content can be granted evenafter the user leaves the targeted location. This is achieved throughthe use of authorized software related to the target location thatgrants the user access to the proxy server. The proxy server can grantthe connection based on authorization protocols utilized by the softwaresuch as a Virtualized Private Network (VPN) or the like. Once the proxyserver recognizes the software, the proxy server can process requestsfor premium content as illustrated in the previous embodiments.Moreover, this allows the user to take advantage of other access pointsto the internet besides the ones related to the targeted location. Forexample, a hotel patron who wishes to access premium content in a cafoutside of the hotel may utilize the hotel's authorized software toaccess the proxy server, despite the user's utilization of the caf'saccess point. The authorized software can utilize a subscription basedservice or can be effective for a certain period of time (for example,the proxy server only authorizes the software for the duration of apatron's stay in a hotel).

FIG. 10 illustrates an example of this implementation.

While outside of the targeted location, the user computer 1000 utilizesthe authorization software 1001 and requests premium content 1002. Theauthorization software forwards its authorization protocols 1003 to theproxy server 1006. If the authorization protocols are accepted, theproxy server will serve premium content back to the user computer,utilizing the previously described embodiments to do so. If theauthorization protocols aren't accepted (due to the user attempting toaccess the proxy server without the authorization software and withoututilizing the service provider of the target location, or due to thelapse of the authorization software, for example), the proxy server willreject the incoming connection and will not deliver the premium content.

FIG. 11 is a block diagram that illustrates an embodiment of acomputer/server system 1100 upon which an embodiment of the inventivemethodology may be implemented. The system 1100 includes acomputer/server platform 1101, peripheral devices 1102 and networkresources 1103.

The computer platform 1101 may include a data bus 1104 or othercommunication mechanism for communicating information across and amongvarious parts of the computer platform 1101, and a processor 1105coupled with bus 1101 for processing information and performing othercomputational and control tasks. Computer platform 1101 also includes avolatile storage 1106, such as a random access memory (RAM) or otherdynamic storage device, coupled to bus 1104 for storing variousinformation as well as instructions to be executed by processor 1105.The volatile storage 1106 also may be used for storing temporaryvariables or other intermediate information during execution ofinstructions by processor 1105. Computer platform 1101 may furtherinclude a read only memory (ROM or EPROM) 1107 or other static storagedevice coupled to bus 1104 for storing static information andinstructions for processor 1105, such as basic input-output system(BIOS), as well as various system configuration parameters. A persistentstorage device 1108, such as a magnetic disk, optical disk, orsolid-state flash memory device is provided and coupled to bus 1101 forstoring information and instructions.

Computer platform 1101 may be coupled via bus 1104 to a display 1109,such as a cathode ray tube (CRT), plasma display, or a liquid crystaldisplay (LCD), for displaying information to a system administrator oruser of the computer platform 1101. An input device 1110, includingalphanumeric and other keys, is coupled to bus 1101 for communicatinginformation and command selections to processor 1105. Another type ofuser input device is cursor control device 1111, such as a mouse, atrackball, or cursor direction keys for communicating directioninformation and command selections to processor 1104 and for controllingcursor movement on display 1109. This input device typically has twodegrees of freedom in two axes, a first axis (e.g., x) and a second axis(e.g., y), that allows the device to specify positions in a plane.

An external storage device 1112 may be connected to the computerplatform 1101 via bus 1104 to provide an extra or removable storagecapacity for the computer platform 1101. In an embodiment of thecomputer system 1100, the external removable storage device 1112 may beused to facilitate exchange of data with other computer systems.

The invention is related to the use of computer system 1100 forimplementing the techniques described herein. In an embodiment, theinventive system may reside on a machine such as computer platform 1101.According to one embodiment of the invention, the techniques describedherein are performed by computer system 1100 in response to processor1105 executing one or more sequences of one or more instructionscontained in the volatile memory 1106. Such instructions may be readinto volatile memory 1106 from another computer-readable medium, such aspersistent storage device 1108. Execution of the sequences ofinstructions contained in the volatile memory 1106 causes processor 1105to perform the process steps described herein. In alternativeembodiments, hard-wired circuitry may be used in place of or incombination with software instructions to implement the invention. Thus,embodiments of the invention are not limited to any specific combinationof hardware circuitry and software.

The term “computer-readable medium” as used herein refers to any mediumthat participates in providing instructions to processor 1105 forexecution. The computer-readable medium is just one example of amachine-readable medium, which may carry instructions for implementingany of the methods and/or techniques described herein. Such a medium maytake many forms, including but not limited to, non-volatile media,volatile media, and transmission media. Non-volatile media includes, forexample, optical or magnetic disks, such as storage device 1108.Volatile media includes dynamic memory, such as volatile storage 1106.Transmission media includes coaxial cables, copper wire and fiberoptics, including the wires that comprise data bus 1104.

Common forms of computer-readable media include, for example, a floppydisk, a flexible disk, hard disk, magnetic tape, or any other magneticmedium, a CD-ROM, any other optical medium, punchcards, papertape, anyother physical medium with patterns of holes, a RAM, a PROM, an EPROM, aFLASH-EPROM, a flash drive, a memory card, any other memory chip orcartridge, a carrier wave as described hereinafter, or any other mediumfrom which a computer can read.

Various forms of computer readable media may be involved in carrying oneor more sequences of one or more instructions to processor 1105 forexecution. For example, the instructions may initially be carried on amagnetic disk from a remote computer. Alternatively, a remote computercan load the instructions into its dynamic memory and send theinstructions over a telephone line using a modem. A modem local tocomputer system 1100 can receive the data on the telephone line and usean infra-red transmitter to convert the data to an infra-red signal. Aninfra-red detector can receive the data carried in the infra-red signaland appropriate circuitry can place the data on the data bus 1104. Thebus 1104 carries the data to the volatile storage 1106, from whichprocessor 1105 retrieves and executes the instructions. The instructionsreceived by the volatile memory 1106 may optionally be stored onpersistent storage device 1108 either before or after execution byprocessor 1105. The instructions may also be downloaded into thecomputer platform 1101 via Internet using a variety of network datacommunication protocols well known in the art.

The computer platform 1101 also includes a communication interface, suchas network interface card 1113 coupled to the data bus 1104.Communication interface 1113 provides a two-way data communicationcoupling to a network link 1114 that is connected to a local network1115. For example, communication interface 1113 may be an integratedservices digital network (ISDN) card or a modem to provide a datacommunication connection to a corresponding type of telephone line. Asanother example, communication interface 1113 may be a local areanetwork interface card (LAN NIC) to provide a data communicationconnection to a compatible LAN. Wireless links, such as well-known802.11a, 802.11b, 802.11g and Bluetooth may also used for networkimplementation. In any such implementation, communication interface 1113sends and receives electrical, electromagnetic or optical signals thatcarry digital data streams representing various types of information.

Network link 1113 typically provides data communication through one ormore networks to other network resources. For example, network link 1114may provide a connection through local network 1115 to a host computer1116, or a network storage/server 1117. Additionally or alternatively,the network link 1113 may connect through gateway/firewall 1117 to thewide-area or global network 1118, such as an Internet. Thus, thecomputer platform 1101 can access network resources located anywhere onthe Internet 1118, such as a remote network storage/server 1119. On theother hand, the computer platform 1101 may also be accessed by clientslocated anywhere on the local area network 1115 and/or the Internet1118. The network clients 1120 and 1121 may themselves be implementedbased on the computer platform similar to the platform 1101.

Local network 1115 and the Internet 1118 both use electrical,electromagnetic or optical signals that carry digital data streams. Thesignals through the various networks and the signals on network link1114 and through communication interface 1113, which carry the digitaldata to and from computer platform 1101, are exemplary forms of carrierwaves transporting the information.

Computer platform 1101 can send messages and receive data, includingprogram code, through the variety of network(s) including Internet 1118and LAN 1115, network link 1114 and communication interface 1113. In theInternet example, when the system 1101 acts as a network server, itmight transmit a requested code or data for an application programrunning on client(s) 1120 and/or 1121 through Internet 1118,gateway/firewall 1117, local area network 1115 and communicationinterface 1113. Similarly, it may receive code from other networkresources.

The received code may be executed by processor 1105 as it is received,and/or stored in persistent or volatile storage devices 1108 and 1106,respectively, or other non-volatile storage for later execution. In thismanner, computer system 1101 may obtain application code in the form ofa carrier wave.

It should be noted that the present invention is not limited to anyspecific firewall system. The inventive policy-based content processingsystem may be used in any of the three firewall operating modes andspecifically NAT, routed and transparent.

Finally, it should be understood that processes and techniques describedherein are not inherently related to any particular apparatus and may beimplemented by any suitable combination of components. Further, varioustypes of general purpose devices may be used in accordance with theteachings described herein. It may also prove advantageous to constructspecialized apparatus to perform the method steps described herein.
